It’s the original vinyl flooring in this case and even though it’s not generally recommended to lay “luxury vinyl planks” on top of it, it usually is not a problem and the customer didn’t want me to tear out the old flooring due to how much extra work that would cause.
I’ve only been doing this for around 6 months so I haven’t had any that special jobs so far but I did a small kitchen remodel to one customer where I tore down the old and build a new one for her which was quite enjoyable job.
My favourite jobs are ones that require creativity and problem solving. When ever I can fix something instead of replacing it is fun. This is a recent example of such job:
It’s honestly easier to list what I don’t do which is building something bigger than a shed, electric work, work inside tanks / wells, challenging tree fellings, jobs that require more than one person such as roofing, asbestos demolition and jobs where I need to deal with refrigerants.
